HDMI Adapter With The Gradual Increase Of Function

HDMI Adapter With the gradual increase of function

As intelligent device occupies more and more important position in people's lives, with the function of increasing, consumption problem also gradually exposed, is becoming more and more people began to used to carry the power adapter, also is the people often say that the charger. What is the difference between this power adapter and the regulator? This article will introduce you.

It is found that the voltage of the power adapter is higher than the value that he marked without loading, and the voltage regulator has always been this value. So what's the difference?

The difference between the power adapter and the regulator

1, the power adapter is a small portable electronic devices and electronic power supply power transformation equipment, generally composed of shell, power supply transformer and rectifier circuit, according to its output type can be divided into the ac and dc output. It can be understood as a voltage converter, such as converting 110-220 volts of ac voltage to a fixed dc voltage.

2. Voltage regulator is the device that makes the output voltage stable. The stabilizer is composed of constant voltage, control circuit and servo motor. When the input voltage or load change, sampling and comparison are made on the control circuit, amplifier, and then drive servo motor rotation, and change the position of the voltage regulator for carbon brush, by automatically adjusting the coil number of turns ratio, so as to maintain the stability of output voltage.

Power adapter in the case of no load voltage is higher, if you pick up the load will find its voltage will drop down, this is due to the action itself limits, just in order to provide an appropriate voltage to the load, and the main effect of voltage stabilizer is regulated, it will be through its voltage stability to a certain extent, more than or less than this value it has action, power adapter, there is no this function. These two can distinguish according to usage, if is the place where the load power demand is not high can substitute each other, but if the load of power demand is higher, even 1 v voltage change is not, then you must use the voltage stabilizer, burn it otherwise not load to the power supply.

Editing by method

Usage of the adapter pattern:

Using a class that inherits interfaces and known classes, using methods and attributes defined in a known class, implements the definition in the interface (mainly using the method of overloaded interface methods). Using this class as a base class for other business classes, this class fits with the interfaces and known classes. If the class changes, you can simply modify the class adapter to satisfy the implementation of the interface.

Adapter type: needle transfer seat.
